Linux Processes and Services

Monitor CPU Memory and Load

Interpret CPU use, memory pressure, load averages, and process evidence together instead of treating one large number as a diagnosis.

UNTIMED COACHING

Practice before the pressure

Use feedback to correct the model, not merely memorize an option position.

GUIDED PRACTICE

Practice the lesson questions

Answer normal lesson questions without a timer. Every answer includes an explanation, and incorrect answers can be tried again before continuing.

CONCEPT MODELS

See the lesson as a system

Use these visual guides to connect the key ideas before answering the questions.

From CPU utilization to Swap activityConnect cpu utilization with load average, memory availability, and swap activity.
From CPU utilization to Swap activityA learning path connects four specific concepts used in monitor cpu memory and load and states the outcome of each one.
CPU utilizationSustained demand is distinct from spikes
Load averageShort and longer demand trends are visible
Memory availabilityUsable memory headroom is estimated
Swap activityActive pressure is separate from old allocation
Process correlation: command and checksConnect process correlation with the starting command, expected result, and specific safety boundary.
Process correlation: command and checksA practical check connects process correlation to the relevant command, expected evidence, and caution.
Process correlationFocus on process correlation
Starting commandRun ps -eo pid,user,state,%cpu,%mem,cmd
Expected resultSpecific processes explain the measured pressure
Safety boundaryStopping a process may disrupt dependent work
